The demand for subassembly S is 100 units in week 7. Each unit of S requires 1 unit of T and 2 units of U. Each unit of T requires 1 unit of V, 2 units of W, and 1 unit of X. Finally, each unit of U requires 2 units of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.

*Construct a product structure. Identify all levels, parents, and components.

1. (Use the following grid to draw the product structure BOM)

1. Same scenario as above. (Use the following grid to draw the time-phased product structure). What is the overall lead time?

*Construct a product structure. Identify all levels, parents, and components.

2. Given the following BOM and available on-hand inventory, compute the new requirements for all the dependent items for a batch of 70 units of the Bracket.

3. Develop a complete net material requirements plan for the production of following MPS and prepare the ?exceptions? report.
